No. 752,993, filedAug. 15, 1968 and now abandoned.

This invention relates to a locking device for movable leaves such asdoors and window panes.

As is already known, it frequently proves necessary to lockmovableleaves at a number of different points when said leaves have a tendencyto deform by reason of their construction or dimensions. For example,locking is necessary when a P leaf of this general type consists of aframeless pane of hard 7 glass, a sheet of plastic material or a glasswindown pane surrounded by a lightweight frame. When locked in theclosed position, the leaves are well seated on their casings and canadditionally withstand any pressure to which they may be subjectedwithout deformation, especially under the action of wind.

To this end, use has been made of devices comprising a main lockconsisting of a catch which may or may not be rotatably mounted on theleaf and which is actuated by means of a handle, said catch beingadapted to cooperate with a staple which is fixed in oppositely facingrelation on the casing, and one or a number of auxiliary locks of thelatch type which are controlled independently of the main lock and evenfrom a distance, especially by means of pulling handles and cables.

These devices have the disadvantage of requiring a number of separateoperations both at the moment of locking and at the time of unlocking;furthermore, if the auxiliary locks are actuated before the proper time,the leaf is liable to be damaged at the moment ofclosure.

Use has also been made of another class of devices which comprise aplurality of catches mounted on the leaf and adapted to cooperate withstaples mounted in opposite relation on the casing, said catches beingactuated simultaneously by means of a central control system carried bythe leaf.

In the devices last-mentioned, the connecting members are cumbersome,increase theweight of the leaf, reduce the field of visibility and areunattractive. In order tocircumvent these disadvantages, it has beenproposed to conceal the connecting elements to a partial extent withinthe leaf frame. However, the recesses which are thus made necessary areusually detrimental to the rigidity of said frame.

In any case, the devices just referred-to cannot be employed onframeless panes of hard glass without presenting major-difficulties; infact, the attachment of such devices to glass panes of this type wouldentail high capital cost and would prove unacceptable to users.

The aim of this invention is to overcome the disadvantages noted above.

In accordance with the invention, the device for locking movable leavessuch as window panes and comprising a main lock provided with a catchmounted on the leaf and adapted to cooperate with a box-staple fixed inoppositely facing relation on the casing against which the leaf isbrought to bear in the closed position and at least one auxiliary lockessentially comprises a system for the remote operation of the auxiliarylock by the catch of the main lock by means of a mechanical connectionsystem carried by the casing.

It is thus possible in a single operation to carry out the synchronizedactuation of all the closure members.

In a preferred manner, the connection system comprises a slide-blockwhich is housed within the box-staple, said slideblock being connectedto motion-transmission means carried by the casing and terminating in arocking-latch which forms part of the auxiliary lock. Also as apreferred feature, the slide-block is provided with a shaped recess foraccommodating the extremity of the catch which is rotatably mounted onthe leaf.

It is apparent that, during the movement of closure of the main lock,the slide-block is displaced by the catch, thereby producing the closureof the rocking-latch of the auxiliary lock. Fastening of the leaf isthus carried out by means of the two locks which work simultaneouslyunder the action of the mechanical connection system.

This locking system has the advantage of being applicable to differenttypes of movable leaves and especially to those which open by swinginginwards about the lower horizontal crossmember of the casing and tothose which open in a pivotal motion about a vertical upright member ofthe casing.

Another field of application of the invention which is of particularinterest relates to windows which are operated not between two positionsbut between three positions: a closed position, a top-opening positionand a side-opening position. Windows of this type combine the advantagesof the two above-mentioned modes of opening by permitting of pivotalmotion either about a horizontal axis or a vertical axis.

In this particular application, the main lock and the auxiliary lockeach have three associated positions: the first is an open position forthe main lock and for the auxiliary lock, the second is a closedposition for the main lock and for the aux- 0 iliary lock and the thirdis an open position for the main lock and a closed position for theauxiliary lock.

By virtue of this arrangement, all the window-opening operations can becarried out by means of a single main lock which actuates a suitablenumber of auxiliary locks from a distance by means of a connectionsystem carried by the eas- In a preferred embodiment, the locking devicecomprises two sets of auxiliary locks, the first set being mounted alongthe bottom member of the casing and the second set being mounted on theside of the casing opposite to the main lock; each auxiliary lockcomprises two hinges between which a movable pin actuated by the mainlock serves to establish a pivotal connection.

It is clear that, depending on the position given to the main lock, allthe auxiliary locks are closed at the same time or alternatively one orthe other of the two sets mentioned above. When only one set is in theclosed position, the main lock is in the open position and the leaf ispermitted to open by carrying out a pivotal movement about the closedlocks which perform the function of hinges. These improvements are ofoutstanding interest from an industrial standpoint in the case of windowpanes of the type consisting of a sheet of hard glass which is at leastpartly frameless.

Further properties and advantages of the invention will become apparentfrom the description which follows below, reference being had to theaccompanying drawings which are given by way of example without anylimitation being implied, and in which:

Referring now to FIG. 1, there is shown a pivoted window which comprisesa stationary casing 1 of wood, for example, and a pane 2 of hard glass,referred-to hereinafter as a leaf. Said leaf is capable of moving aboutthe horizontal axis which passes through two pivots 3 and these latterare rigidly fixed to the upright members of the casing l on which saidleaf is mounted.

Leak-tightness of the window in the closed position is by means of aseal 4 which is mounted in the opening of the casing 1.

The locking device in accordance with the invention as employed for awindow of this type comprises a main lock A which is fitted at thebottom of said window. Said main lock comprises a catch 5 mounted on theleaf 2 and a box-staple 6 fixed in oppositely facing relation thereto onthe lower cross member 8'of the casing 1. At the top of the window, thelocking device further comprises an auxiliary lock 7 which is housed inthe upper crossmember 9 of the casing I. Said two locks A and 7 areplaced along the vertical axis ofsymmetry of the window and a cableconnection system 10 serves to connect the box-staple 6 to the auxiliarylock 7.

As illustrated in greater detail in FIGS. 2, 3 and 4 in which the mainlock A is drawn to a larger scale, the catch 5 (shown in FIG. 2) isintegral with an operating handle 11 which is substantially at rightangles thereto. The catch 5 is rotatably mounted on a pivot-pin 2 whichis perpendicular to the leaf 2 and the base 13 of which is screwed to aclamping plate 14 placed in oppositely facing relation thereto on theother face of the leaf 2.

The box-staple 6 is closed by means of a detachable front cover 15. Thelarge face of said box-staple which is opposite to the cover 15 isscrewed into the lower crossmember 8 and is mounted flush with the edgeof this latter in the longitudinal direction. The box-staple 6 isprovided with an engagement slot 16 formed in a small plate 17 which isset in a groove 18 formed along an opening of said face. The box-stapleengagement slot 16 is provided on the side nearest to the crossmember 8with a skew 19 which slopes away from said crossmember 8 in a firstsection 190 then remains parallel to said crossmember in a secondsection 19b, said two sections 190 and 19b being separated from eachother by a stop-boss 21 for arresting the catch 5 which, in the closedposition, moves into position against the second section 19b of the skew19.

A slide-block 22 of rectangular cross section is slidably mounted on alongitudinal rod 23 inside the box-staple 6 and is guided in itsdisplacement by the vertical walls of said boxstaple. The slide-block 22is provided at the top with a shaped recess 24 for receiving the tip ofthe catch Sand at the bottom with a lug 25 in which a bore 26 is formedparallel to the guide rod 25 so as to provide a passageway for the cable10 which is brought in through an opening 27 of the box-staple 6 andsecured at the outlet of the bore26 by means ofa cable clamp 28 which isapplied against the lug 25. The guide rod 23 which is supported by theend faces of the box-staple 6 is held in position by means of anend-clip 29. Said clip is applied within a housing which is symmetricalwith the recess in which the head 31 of said guide rod 23 is embedded.The V-shaped recess 24 has a vertical bearing wall 24a.

Reference will now be had to FIGS. 5, 6 and 7 in which the auxiliarylock 7 is also shown on a larger scale. From these figures, it isapparent that said auxiliary lock comprises a box 32 which is open ontwo sides and a rocking-latch 33 which is force-fitted on a transversespindle 34, the ends of which are mounted for rotation in bearings whichform part of the base 35 of the box 32. The box is housed within ahollowed-out portion 30 formed in the front portion of the uppercrossmember 9 so that its base 35 and fixing flanges 36 project aslittle as possible from the horizontal wall of the rebate formed in thecrossmember 9 in order not to interfere with the movements of the leaf2. v

The rocking-latch 33 which is illustrated in FIG. 8 has two arms 37 and38 which are inclined to each other at an angle of approximately and thepivotal motion of which is limited to an amplitude of about 45 by ashaped opening 39 of the base 35 into which the upper arm 37 is adaptedto pass. Two bores 41 and 42 are formed at the extremity of the upperarm 37: the bore 41 serves to secure the head 43 of the sliding cable 10which passes out of the box 32 through the bore 44; the bore 42 servesas a point of attachment for a restoring spring 45, the other end ofwhich is attached to the box 32.

The other arm 38 forms a catch and is capable either of angulardisplacement outside the box 32 in such a manner that the side 47 ofsaid arm is brought to bear on the leaf 2 in the closed position or ofcomplete withdrawal into the cavity 46 formed beneath the base 35 of thebox 32 in order not to interfere with the movements of the leaf 2. Theside 47 (as shown in FIG. 8) is a flat surface which is inclined at anangle of ap proximately 3 to the plane located at right angles to thepivotal axis or spindle 34 and to which is added another angle ofinclination of approximately 4 with respect to a right section. It isunderstood that this tapered shape facilitates engagement with the leaf2 and permits the exertion of a progressive thrust on this latter.

On the side opposite to the leaf 2, the two arms 37 and 38 are providedwith diagonal edges in order to reduce the weight of the rocking-latch.

The sliding cable 10 of the mechanical connection system (as shown inFIGS. 9 and 10) which starts from the rockingcatch 33 and terminates atthe slide-block 22 runs within a sheath 48. Said sheath is fitted in arebate 49 which is formed around the periphery of the casing 1 and atthe front edge of this latter. Said rebate 49 which is formed prior toinstallation around the entire periphery for reasons of convenience isin fact intended to accommodate the cable 10 only over one-half saidperiphery, namely the half which is shown in the figure on theright-hand side of the vertical plane of symmetry of the window. Acover-plate 51 made up of four miter-jointed strips is fitted over therebate around the entire casing.

The locking device in accordance with the invention as hereinabovedescribed is in the operative condition when the turns of the restoringspring 45 of the auxiliary lock are in contact with each other and thesliding cable 10 has been tensioned by displacement of the cable clamp28 which is applied against the slide-block 22, thereby bringing saidslide-block to bear against that endwall of the box-staple 6 which islocated on the cable inlet side.

In order to close the pivoted window which is illustrated in FIG. I, theoperator takes hold of the operating handle 11 and draws this lattertowards him, thereby causing the rotation of the leaf 2 about the pivots3, said leaf being then applied against the rebates of the crossmembers8 and 9 of the window-casing 1 and brought into contact with the seal 4.

In order to lock the leaf 2 in the closed position, the operatorcontinues to exert a pull on the operating handle 11 while rotating thislatter in the direction indicated by the arrow H in FIG. 2. The tip ofthe catch 5 then engages in the box-staple slot 16 as shown in FIG. 3while bearing on the skew section 19a. It is apparent that, as theoperator continues his movement in the direction of the arrow H, theleaf 2 applies an increasing pressure against the seal 4 which is placedat the bottom of the rebate of the lower crossmember 8 by virtue of theobliquity of the skew section 19a which slopes progressively away fromthe plane of the casing 1. Thereupon, the catch 5 passes over the boss21 which maintains the locking action, then slides over the skew section19b which is parallel to the plane of the casing 1. As a result of thisoperation, that-portion of the leaf 2 which is located below the axisformed by the pivots 3 is suitably closed and locked in position; goodleak-' then into the shaped recess 24 and comes into contact with thevertical wall 240 of this latter. Under the effort exerted by the catch5, the slide-block 22 moves horizontally inthe direction of the arrow Kand causes the displacement ofthe cable 10. As a result of the actionproduced by the cable which is secured at the other end thereof to thelatch-arm 37, the rocking-latch 33 performs a pivotal movement in thedirection of the arrow L (as shown in FIG. 5) and lowers its arm 38which presses the leaf 2 progressively against the seal 4 which isplaced within the rebate of the upper crossmember 9. During this pivotalmovement, the restoring spring 45 is progressively stretched. Thepivotal movement stops when the arm 37 of the rocking-latch 33 isapplied against the sloping wall 390 of the opening 39 of the box 32',the amplitude of this movement is 45 and permits the arm 38 to take up aposition at an angle of 45 to the horizontal. Inasmuch as the cable 10is no longer capable of sliding, the catch 5 is then immobilized in itsturn. As a result of the pivotal movement of the rocking-latch 33, thatportion of the leaf 2 which is located above the axis formed by the twopivots 3 is thus suitably closed and locked in position; goodleak-tightness is ensured in this zone by virtue of the pressure appliedbythe leaf2 against the seal 4.

In order to carry out the unlocking operation, it is only necessary torotate the operating handle 11 in the direction opposite to the arrow H.The catch 5 accordingly slides over the skew section 19b in thedirection of the boss 21, passes over said boss, continues to move whileremaining in contact with the sloping skew section 19a and finallypasses out of the box-staple engagement slot 16. At the same time, theslideblock 22 which is controlled by the restoring spring 45 of theauxiliary lock 7 has followed the backward movement of the catch 5 whileremaining in contact with the tip of this latter by means of thevertical wall 240 of the shaped recess 24. The movement of theslide-block 22 in the direction opposite to the arrow K stops when saidslide-block is applied against the wall of the box-staple 6 which islocated on the same 'side as the cable 10 and, in this position, theshaped design of the recess 24 permits the release of the tip of thecatch 5. Moreover, in the auxiliary lock, the action of the restoringspring 45 becomes prepondcrant, the rocking-latch 33 pivots in thedirection opposite to the arrow L and its arm 38 withdrawn into thecavity 46 of the box 32, thereby completely releasing the leaf 2.

The pivoted window can then be opened again by pushing the operatinghandle 11 in the outward direction.

In a preferred manner, the moving components of the locks of the lockingdevice in accordance with the invention, that is to say the slide-block22 and the rocking-latch 33, are formed of plastic material such aspolyamide. The sliding cable 10 is preferentially of the type employedfor bicycle brakes. The plate 17 in which is formed the box-stapleengagement slot 16 is preferably made of stainless steel.

The application of the locking device which has just been describedmakes it possible in an advantageous manner to lock or to unlocksimultaneously both the top and bottom portions of the leaf 2 in asingle movement of the handle 11. The system of connection between thetwo locks A and 7 is remarkably simple and is fully concealed so thatthe visible ancillary components on the window are reduced to a minimum.Moreover, the device is both inexpensive to produce and easy to install.

The locking device hereinabove described comprises motion transmissionelements which have been mounted in the right-hand portion of the windowcasing. Said elements can also be fitted in the left-hand portion but inthis case the device is arranged in its symmetrical form. The operationaccordingly differs in that the rotation of the operating handle 11 andof the catch 5 takes place in the direction opposite to the arrow H forthe locking operation and in the direction of said arrow for theunlocking operation.

Thus, in FIG. 11, the device according to the invention is applied tothe longitudinal fastening of a casement window, or window-leaf whichpivots about a lateral vertical axis.

This window comprises a fixed casing 61 and a leaf 62 which is pivotallymounted on an upright member 64 of said casing 61 by means of two hinges63. The leaf comes into the closed position against a rebate (not shownin the figure) which is formed in the opposite upright member 65.

This application differs from the first in that the components of thedevice are displaced in order to fasten the free vertical edge of theleaf 62 and in that said components are disposed symmetrically. I

The operation of the device remains the same, the handle 11 being alsooperated in the downward direction.

In this new application, the advantages of the device are retained.

In FIG. 12, the device according to the invention is applied to thelongitudinal fastening of one of the edges of a centrally pivoted windowpane.

The window comprises a fixed casing 71 and a pivotal leaf 72 which isrotatable about a vertical axis which passes through two pivots 73, saidpivots being rigidly fixed to the crossmembers of the casing 71 and saidleaf being mounted on said pivots.

This third application differs from the first in that the devicecomprises two auxiliary locks 7a, 7b. Said locks are remotely operatedin series by means of the sliding cable 10 and can also be remotelyoperated separately by two sliding cables which are both secured to theslide-block 22 of the box-staple 6.

The operation of the device as thus modified is the same as that of thefirst application and provides the same advantages.

The third application referred-to is of interest for the purpose oflocking pivotal leaves of substantial height. 7

In the fourth application which is illustrated in FIG. 13, two devicesin accordance with the invention are mounted on a same pivoted windowfor the transverse fastening of the leaf 82.

The first of these devices which is mounted in the right-hand portion issimilar to the third application and comprises two auxiliary locks 7a,7b which are mounted on the upper crossmember of the casing 81, one atthe center of the casing and the other at one end ofthe casing.

The second device is identical with the second application (handle 5a,lock 7c).

The devices referred-to operate independently and are advantageouslyemployed for the purpose of locking pivotal leaves of very substantialwidth.

The embodiment which is illustrated in FIG. 14 is an alternative form ofthe locking device according to the invention,

wherein the box-staple 6 is connected to its auxiliary lock 7 (notshown) by means of a transmission member consisting of a link-rod 83.This alternative form of construction differs from the first applicationof the device in that the link-rod 83 connects the slide-block 22 to therocking-latch 33 of the lock 7 instead of the sliding cable and that arestoring spring 84 which is interposed between the slide-block 22 andthe base of the box-staple 6 replaces the restoring spring 45 of therocking-latch 33.

The link-rod 83 is secured to the lug 25 by means of two nuts 85 and 86which are applied against the opposite faces of the lug 25. In thisapplication, the connecting system com prises a link-rod system whichincludes articulated members 87 forming bellcrank levers.

In a specific application of the invention which will now be described,the window comprises a fixed casing 101 (as shown in FIG. and aframeless pane 102 of hard glass which can be pivoted at will about alower horizontal axis or about a lateral vertical axis. A flexible seal104 (shown in FIG. 23) is secured to the casing 101 and serves as a stopfor the window pane 102. Y

The locking device comprises on the left-hand side of the window a mainlock A which in turn comprises a catch I05 mounted on the window pane102 and a box'staple 106 which is fixed in oppositely facing relation onthe left-hand upright member 103 ofthe window casing 101.

The locking device further comprises four auxiliary locks 107 which arefitted on the right-hand side and at the bottom of the window. Two ofsaid locks, namely the locks 107a, are secured to the lower crossmember108 of the window casing 101 and to the corresponding edge of the windowpane 102. Theother two auxiliary locks, namely 107b, are secured to theright-hand upright member 110 of the casing 101 and to the correspondingedge of the pane 102.

A link-rod system B carried by the window casing 101 connects the mainlock A to the four auxiliary locks 107.

The catch 105 of the main lock A (as shown in FIGS. 16 and 17) consistsof a plate having a substantially triangular contour which is capable ofsliding along the window pane 102. One of the summits of said plateconstitutes a nose which projects beyond the edge of the pane 102 andcarries a lateral stud 116. The side of the catch 105 which is remotefrom the nose carries a rack 115 which is parallel to the edge of thepane 102 and projects from the reverse face of the catch 105 t withrespect to that which carries the stud 116.

The rack 115 is adapted to engage with a toothed sector 114 which isintegral with a shaft 112 having a square end on which is fitted anoperating lever 11] The shaft 112 is adapted to pass through a supportplate 113 which is fixed on the window pane 102 and which is recessed toaccommodate the catch 105, the rack 115 and the toothed sector 114.

The box-staple 106 comprises a casing 117 which is inserted in a recess117a of the upright member 103 of the window casing 101 and a coverplate 118 which is mounted flush with said window casing. Thecover-plate 118 is provided on cover plate side facing opposite to thecatch 105 with two recesses 119a and 119b separated by a central boss120 which is curved towards the interior of the box-staple 106, as shownin FIG. 17.

A block 121 which is adapted to slide vertically in the interior of thebox-staple 106 is provided with a bore 122 which is intended to receivethe stud 116. This slide-block 121 is coupled by means of a tenon 123 toa flat bar 124 which constitutes one component of the link-rod system B.Said flat bar 124 which is housed within a vertical groove 125 of theupright member 103 is adapted to penetrate into the box-staple 106through two notches 126 of the box-staple casing 117. When theslide-block 121 takes up either one or the other of the end positions inwhich it is abuttingly applied against one of the walls of thebox-staple 106, the bore 122 is located substantially at the same levelas the center of one of the recesses 119a and 119/).

The flat bar 124 terminates at the upper extremity in a rightanglcdportion which is directed towards the window pane 102 and constitutes anadditional locking member 127. When the slide-block 121 takes up a meanposition within the box-staple 106, the locking member 127 engages in acrossmember 128 which is fixed along the upper edge of the window pane102 and which projects beyond the edge of said pane on the sidecorresponding to the catch 105. On the contrary, when the slide-block121 takes up one of its end positions, the crossmember 128 is releasedfrom the auxiliary lock 127.

By following the link-rod system B, it is seen that the flat bar 124 ispivotally coupled at the lower end by means of a motion-transmissionchain 131 with a horizontal rod 132 which is enclosed within a sheath129 and fitted within a groove 133 of the bottom crossmember 108. At theend remote from the motion-transmission chain 131, the rod 132 ispivotally coupled by means of another transmission chain 134 with avertical rod 135 which is also sheathed and fitted within a groove 136of the right-hand upright member 110. The rod 132 is connected to theauxiliary locks 107a and the rod 135 is connected to the auxiliary locks107b as will be explained hereinafter.

Referring now to FIG. 15 and to FIG. 18, it is apparent that eachsimilar lock 107 comprises a hinge component 141 which is secured to thewindow casing 101 and a hinge component 143 which is secured to thewindow pane 102, said hinge components being capable of cooperating witheach other by means ofa movable pin 145 which corresponds to therocking-latch of the previous embodiments. The stationary hingecomponent 141 has two lateral extensions in the form of brackets 146 andthese latter are joined at their extremities by threaded rods 148 whichare forcibly inserted in the window casing 101. The rod 132 is adaptedto pass between the brackets 146 and is provided between these latterwith a notched portion 149 into which penetrates the lug of a slide 150,said slide being integral with the movable pin 145 which is slidablyfitted within the hinge component 141. The movable hinge component 143which has the same internal diameter as the hinge component 141 issecured to the pane 102 by means of screws.

The movable pin 145 which is coupled to the link-rod system B by meansof the slide 150 is capable of taking up three positions correspondingto the three positions of the catch 105;

in a first or so-called disengagement position, the mova ble pin 145 isfully withdrawn into the hinge component 141;

in a second or so-called semi-engagement" position, said pin projectsfrom the hinge component 141 to a distance which is substantially equalto one-half the length of the hinge component 143;

in a third or so-called engagement position, said pin projects to adistance which is substantially equal to the length of the hingecomponent 143.

In addition, the respective positions of the four movable pins 145relative to the link-rod system B are such that all the auxiliary locks107 are in the semi-engagement position at the same time when the mainlock A is in the closed position as shown in FIG. 15; when the main lockA is in its first open position and the operating lever 111 is thusdirected upwards so that the nose of the catch 105 is located oppositeto the recess 119a, the auxiliary locks 107a are accordingly in theengagement" position and the auxiliary locks 107b are in thedisengagement" position, as shown in FIG. 19; when the main lock A is inits second open position and the operating lever 111 is thus directeddownwards so that the nose of the catch 105 is located opposite to therecess 11%, the auxiliary locks 107a are accordingly in thedisengagement position and the auxiliary locks 107b are in theengagement position, as shown in FIG. 20.

Finally, the equipment of the window is completed by an articulatedopening arm 151 of known type (as shown in FIG. 15), said arm beingsecured at one end to the crossmember 128 which is located above thepane 102 and at the other end to the right-hand upright member 110 ofthe casing 101.

The operation of the locking device is as follows:

a. when the window is in the closed position, the pane 102 is appliedagainst the casing 101 and the operating lever 111 is in a substantiallyhorizontal position, as shown in FIG. 15. The nose of the catch 105 isengaged within the box-staple 106 beneath the boss 120 and forced bythis latter towards the interior of the box-staple and the stud 116 ishoused within the bore 122 of the block 121. The four auxiliary locks[07 are in the semiengagement" position and the additional lockingmember 127 is in contact with the crossmember 128. The pane 102 istherefore secured on all four sides. Furthermore, the pane is appliedagainst the seal 104 under pressure as a result of the engagement of thenose of the catch 105 beneath the boss 120, thereby ensuring hermeticclosure of the window.

b. if the operating lever 111 is displaced upwards by onequarter of arevolution in the direction of the arrow F as shown in FIGS. 19 and 21,the nose of the catch 105 comes opposite to the recess 119a. At the sametime, the auxiliary locks 107a are moved to the engagement" position andthe auxiliary locks 1071) are moved to the disengagement position.Finally, the additional'locking member 127 is lifted above thecrossmember 128. if the operating lever 11] is pulled towards the user,the catch 105 is released, thereby permitting the downward pivotaldisplacement of the window pane 102 which is now retained only by theauxiliary locks 107a which perform the function of hinges: this is thecondition of opening about a horizontal axis in which the inward swingof the pane 102 is limited by the angular opening of the articulated arm151.

. if the pane 102 is thrust back against the casing 101, the nose of thecatch 105 comes into position opposite to the recess 119a and the stud116 engages in the bore 122, with the result that the link-rod system Bis coupled with the catch 105. By rotating the operating lever 111 inthe direction G up to the horizontal the nose of the catch 105 isengaged beneath the boss 120, thereby compressing the seal 104. At thesame time and under the action of the link-rod system B, the movablepins 145 of the auxiliary locks [07b engage to half the distance oftravel within the corresponding hinge components 143 and the movablepins of the auxiliary locks 107a withdraw to half the distance oftravel, with the result that all the auxiliary locks 107 are located inthe semiengagement" position. Finally, the additional locking member 127returns opposite to the crossmember 128, whereupon the window is closed.

d. if the operating lever 11] is then displaced downwards by one quarterofa revolution in the direction G as shown in FIGS. 20 and 22, the noseof the catch 105 comes. opposite to the recess 11%; the auxiliary locks107a are brought to the disengagement" position and the auxiliary locks10717 are brought to the engagement position. The additional lockingmember 127 is displaced downwards below the crossmember 128. The windowcan then be opened in a movement of rotation about a lateral verticalaxis.

In this method of operation, it is essential to note on the one handthat the catch 105 cooperate with the link-rod system B only if the pane102 is in contact with the casing 101 and, on the other hand, that it isimpossible to change over from one mode of opening to the other withoutcompletely closing the window. These technical effects of the lockingdevice eliminate any danger of mishandling which would otherwise result,for example, in falling of the pane 102.

The locking device in accordance with the invention also makes itpossible to provide windows having two modes of opening in which alloperations are carried out by means of a single handle and in which thesystem of connection between the different components which serve toclose the window is Finally, the simplicity and ruggedness of the devicepermit of economic manufacture and maintenance and also guarantee a longservice life.
